Numa

Arc Testnet

AI stablecoin copilot on Arc. Soulbound ERC-721 agents hold their own history, a multichain CCTP bridge moves USDC without wrapping, and one conversational agent drives swaps, yield routing and onchain scans.

Portrait of Joy Madhu

Joy Madhu

Web3 & DeFi Engineer · Dhaka

Three years deep in crypto, building from Dhaka for teams everywhere. I ship DeFi protocols, token launchpads and agent tooling across EVM chains and Solana, and I keep going after the hard parts: FHE circuits, TEE enclaves and MEV resistant market structure.

Everything here is deployed, public and yours to audit. If something on this page looks like what your protocol needs, my inbox is open.
